About

I'm a fifth-year Ph.D. student at Stanford University in the Computational Imaging Lab. My work is at the intersection of optimization, machine learning, optics, and hardware. Along these lines I've been developing next-generation computational LIDAR systems and algorithms for imaging around corners. I'm generally interested in problems in 3D imaging, inverse scattering, optimization, and computer vision, with a goal of developing computational methods to push the boundaries of current imaging capabilities. My work is relevant to a broad range of applications including autonomous vehicle navigation, medical imaging, remote sensing, and robotic vision.
